Application filed May 19,

To all whom timely concern:

Beit known that I, JocnLYN EMILE OL- Livinn, residing at La VignetteSit-Gervais, Department ot the Haute-Savoie, France, have inventedcertain new and useful I1nprovements in Driving Devices for Autosleds,ot which the following is a specification. Y

This invention relates to an automobile sled and the driving meanstherefor, and more particularly to a non-slipping driving wheel havingdoubly-pivoted spikes, as set forth in Patent No. 1,225,999 dated May15, 1917, in which the wheel is provided with links or rods pivotedthereupon, arms pivoted to the said links, and spikes disposed upon theouter ends of the said arms and adapted to assume a swinging movement,the links or rods being preferably mounted so as to pivot not directlyupon the wheel, but upon annular rings secured thereto.

My invention has as its object to provide ditl'erent means :torobtaining a demountable assembling of the annular rings with the wheel,tor the purpose of affording a more rapid and convenient mounting anddemounting ot the said rings and of the entire assemblage of thenon-slipping teeth.

The accompanying drawings represent by way et example a number otpractical embodiments of this invention.

In Figs. 1 and 2, the annular rings upon which the spikes D are mountedby means ot the double pivoted links, are each composed to twosemi-c`ircular rinOs 1 and 1 having a right angled section. Fliese ringsare assembled with the tour rods '2 by means of the straps 3 which arebolted upon one flange ot' the ring and thus clasp the journaled portionformed on each end ot' the rods 2 and having a shoulder on either sidethereof. The said rods are secured tothe wheell in the following manner.Each lrod 2 contains two journaled` portions l upon its ends, which areadapted to rotate within the straps 3, and a portion 5 of square orhexagonal term adapted to be operated by means of a wrench or othersuitable device, as well as two portions 6, 6', screw-threaded incontrary sense and having disposed thereon the jaws 7, 7 f in the formof nuts. Fig. 8 represents a front elevational view ot a jaw member oithis kind. By using a wrench upon i920.v serial No. 382,599.

the portion 2 to effect the rotation of the rod 2 theljaws 7, 7 arebrought together or vseparated in orderv to clamp the Vedges oi thetelly or to separate the yjaws therefrom, for the purpose of mountingthe rod '2 upon the felly or demounting the same, and consequently thesaid annular rings together with theirassemblage ot pivoted spikes. L

Fig. 3 and also Fig. 4 which is a sectional view along the line IV-IV(Fig. 3), represent an alternative form as concerns the stop or abutmentportion of the link 9 which contains pivoted upon one end thereoil thecorresponding arm ot' the spike D. The said link is provided with theprojection 10 adapted to strike vagainst one flange of 'the angle memberconstituting the ring 1, thus preventing'the link 9 from swingingclockwise of the approximately radial line passing through the center ofthe wheel, as shown in Fig. 3. The two studs provided with the shoulders11 and 12 are assembled respec-k tively by riveting and by screw threadand nut, upon the arm 8 of the spike and upon one ange of the angle ironannular ring, 1, constitute pivots for the-link 9. An alternative formis represented in Fig. 15 and in Fig. 16 which is a sectional view alongthe line XVI-XVI (F ig. 15), the projection 10 of the link 9 beingshaped as represented in Fig. 16, for the purpose ot striking againstthe rim ot one flange ot the angle member 1.

Figs. 5, 6 and 7 represent another method of mounting the annular rings.In this case the rings have aT section and are assembled with the rods 2by means of the nuts 13, 13 screwed upon the threaded ends 14, 14: oftherod 2, these ends Ihaving asmaller diameter th'an'the main part ofthe'rod and being adapted to lit into suitable slots 15, 15 in therespective annular rings. Forthe purpose of holding the twosemi-circular rings' v 1, 1, tightly andsecurely upon the rod 2 which islocated at the joint, the arrangement shown in Fig. 7 can be employed.VEach oi the semi-circular rings 1, 1 carries tvvo small cylindricalstuds'16, 16 riveted to the corresponding ring 1, 1; a plate 17 havingtwo holes corresponding t0 the studs 16, 16 is placed upon the two studswhich enter the respective holes therein; the plate is also providedwith a central hole adapted to receive the end 14 of the rod 2, and theentire assemblage of these members is held in place by means of the nut13 screwed upon the threaded end 14. Y Y

Figs. 9 and 10 show another method of mounting the annular rings inwhich they are clamped to the telly by means of the jaws 7, 7. In thisarrangement, the jaws 7, 7 arey provided with the flat projections uponwhich are assembled by means of the bolts 18,'the semi-circular rings 1,1, 'these latter having an angle section in the presentcase.

11 represents a method in which each of the semi-circular rings 1 or 1is itself composed of two half members 26, 27 pivoted to each other bythe pin 28. To each of the said members in the shape ot a quarterVcircle 26 and 27 is secured respectively 'the halt jaw 29, 0,V and onpivoting the said members aboutl the pin 28 in order to bring them forinstance into the position represented by the dotted lines 26 27', thehalves of the aw 29, 30 will separate from each other and release theend ot the rod 2. The ends of the semi-circular ring thus formed aresecured to the wheel by means o'f straps and bolts, as shown in Fig. 2.

Fig. 12 represents the annular rings dei mounted and folded up, whereby'the space occupied by the same will be reduced.

In Figs. 15 and 16 is shown an alternative form of the constructionrepresented in Fig. 1. In this form, each of the pivot rods 2 is madehollow and is traversed by a bolt 32 having the head 32 and nut 34, forthe purpose of securing the angle pieces 3l containing pivoted theretothe links 9 of the spikes; the small plates 33 are attached to themembers 31 opposite the rods 2, and these plates are provided with slotsinto which is inserted the bolt 32. Screwing the nut 34 upon thethreaded end of the bolt will effect the tightening oi. the plates 33against the shoulder 35 on the end ot the hollow rod 2, and thisprovides it'or the clan'iping ot the angle members 3.1 with Y referenceto the Ysaid rods 2.

In Fig. 17, the head 32 of the bolt 32 is provided with a spur 36adapted to enter one of the corresponding` holes provided in lthe plate33 and the anglepiece 31.

In Fig. 18, the points of junction of the angle members 1, 1, arelocated in the space between two adjacent shafts or rods 2, and in orderto provide a very reliable assembling, one of the members 1 carries twosmall studs 37 adapted to enter corresponding holes in two small lugs 38which are mounted upon the second member 1.
